The lithosphere is the topmost layer of the Earth and is found on the surface of the planet. It is composed of the crust and the uppermost part of the mantle, and is divided into several large tectonic plates that move and interact with each other. The lithosphere plays a critical role in the Earth's geology, providing the foundation for the continents and the location for most of the planet's geological activity, including earthquakes, volcanic eruptions, and the formation of mountains and other landforms.
The layer of the Earth where the lithosphere is found is called the uppermost layer. The lithosphere is composed of two parts: the crust and the uppermost portion of the mantle. The crust is the outermost layer and is divided into two types: continental crust, which makes up the continents, and oceanic crust, which makes up the ocean basins. The uppermost portion of the mantle lies beneath the crust. Together, the crust and uppermost mantle form the lithosphere.
